With all our energy production however, there is a battle raging on inside our cells. This is because when mitochondria produce ATP, they also produce damaging by-products known as free radicals. Free radicals are also produced by smoking, pollution and sun exposure. Luckily our mitochondria and cells are packed with antioxidants which can neutralize free radicals before they can do too much damage. However, as we age, or when we are unwell, our antioxidant supply diminishes and the free radicals start to take their toll on the membranes, proteins and DNA in our cells. Over the years, this ongoing damage can lead to reduced cellular energy, cellular repair and organ function. This is known as “oxidative stress”, and it is responsible for the visible signs of aging and can even develop into serious health conditions.
Even though our natural antioxidant supply decreases over time, it’s good to know that we can reduce our oxidative stress levels. Eating a balanced diet, exercising regularly and avoiding toxins and environmental stresses all help in this regard, but science does have one more trick up its sleeve.
